In Germany Claims.

I have filed an application in Germany on the 28th April, 1933.

V The present invention relates to line indicators 7 and other guides ormasks for facilitating reade g of the'kind used in connection with copyholders for typewriters. The object of the invention is to provide animproved line indicator, more particularly improved means for feedingthe line indicator. One characteristic feature of the impr'oved deviceis the provision of a feeding member which at the commencement of a 'newlineis operated by the pressure exerted by the 'typist upon the linespaclever or equivalent'device, Thefeeding member,, on being operated,is'rfirst clamped to the line indicator andis then moved to feed theindicator-by a certain adjustable amount. When the force which firstclamps and then feeds the member ceases, that is, whenlthe memberisreleased, a. spring returns the member to its initial position Aspring or other resilient member is interposed in the mechanisminterposed between the line spacing lever and the feeding member so.that during the last portion. of the movement of the spacing lever thefeeding member can. re.- main at rest and in contact with aflstoplimiting the movement'of the feeding member. The employment of a feedingmember which atthecommencement of each feed is clamped to the indicatorand is-disengaged from the indicator at the .end of each operation,and'theemploymen'tof a resilient member in the meansftransmittingmovement to-the feed member, have the advantage that thewholeconstruction of the device becomes extremely simple and reliable inaction and that the device may be very'easily and rapidly adjusted fora-variable feed.

The accompanying drawing showsby'wayof example one constructionembodying the features of the invention, r Fig.' l is a diagrammaticfront View of, proved device, and Fig. 2 shows a detail. v

In the drawing lindicates a rod carrying at its lower end a lineindicator 2 or other guide or maskfor facilitating reading; The rod l is()1)- erated, that is, fed downwardly relatively to the copy by means ofa lever 3, hereinafter referred to as the clamping lever The clampinglever 3 is loosely mountedupon the rod I and the bore of the lever 3 isso constructed thata slight pressure upon the end of the lever willcause the lever to jam upon the rodand become immediately clamped:thereto. Therefore; downward pressure. upon theend of the-lever 3 willcause immethe im-j April 28, 1933 diate'clamping of the lever 3relatively tothe rod 1 so that downward'movement or the lever 3willcause the rod] to be moved downwardly to" feed; the indicatori. Whenthe pressure upon the end of the lever 3 isreleased, aspring acting upontheundersurface of the boss of the lever 3 will return the lever3 to itsinitial position, the rod remaining during thisreturnimovement of thelever 3 stationary; The rod ;l. is guided in a stationary yoke-shapedmember 2| (see Fig. 10

2),.the upper shank l9. of the yokei2l limiting the upward movement ofthe lever3 and the lower shank 20 serving as the abutment of the spring"4; The yoke 2| is carried by a tube 9 which is fixed by means oftwolateral arms or in any. other suitable way to a vertical member ID ofthe frame 1 of the copy-holder. A stop l6 mounted in an opening of thelower shank I20 and accurately adjustable by means of a scale. I 5serves for limitingthe downwardmovement of the lever 3 and therebyadjusting the-amount of feedgiven to the indicator at each operation.

The clamping lever; 3 has; in addition to the bore 'l through which therod I passes, another bore 8' through which the tube-9 passes, 'thelatter bore being sufficiently larger than the outer diameter of thetube 9 ,to avoid any possibility of jamming between the lever 3 and thetube}. The tube 9 has-two longitudinal slotsl l in which is guided a pinl2 which projects from the tube at both ends and rests upon. the upper.surface ofthe lever 3. r The pin is'connected within the tube 9 to amember, preferably a cord [3, which passes over aguide roller 3! and is.connected at its lower end to the upper arm 30 of a double armed leverpivotally mounted at 25 in. a stationary horizontal member 32 of .theframe. .j The lower arm 24 of the lever is adaptedto be acted upon bythe line spacinglveri. Theleverf'30, 24 is provided with a lateral arm26 servingfo r' manual operation independently of the line spacing lever5.,.;The line indicator .Z 'isfturnably mounted: upon the rod 1 by meansofa hub l! in order to facilitate the insertion of the copy sheet l8under the indicator. Moreover, owing to this hinged connection,theindicjat'or 2 has the tendency to rest under its own Weight upon thecopy sheet. In order to adapt; the position of the red I and theindicator. 2 to the position of the copy sheet I8 or the thickness ofthe Q shorthand book, the shanks I9, 20 of the yoke zl. are turnablymounted upon the tube ,9 of the frame Ill. The indicator 2 maybe made ofa transparent flexible material and isprovided at its end with a metalweight 22 for the purpose of obtaining good contact with the copy sheetIll. The rod I together with the indicator 2 may be manually moved ineither direction by means of a handle 23 which is adapted to be folded.The arm 24 of the lever 24, 30 is within the path of the line spacinglever 5 and is, on turning the platen 6 for a new line moved by the linespacer 5. This movement is transmitted by the upper arm 30, the cord l3and pin I2 to the clamping lever 3 and by the latter to the rod l andthe indicator 2. Feeding may be obtained independently of the linespacer by pressure upon the arm 26. In-

stead of operating the clamping lever' 3 by the,

spacing lever 5, the arm 24 may be arranged to lie within the path ofthe carriage 21 so as to be actuated by the carriage. This arrangementis not, however, so advantageous as operation by the line spacing lever.

The frame I 0 of the device is, in the construction shown detachablyfixed to the carriage 21 of the typewriter. The: copy sheet I8 is,supportedby a'plate 28 above the sheet 29 carried by the platen.This'arrar'igement has the advantage that the point of the copy sheet l8which is actually being copied is always approximately vertically abovethe point at which thegtype strikes the paper 29. Consequently thetypist has no difficulty in finding at anytime the word to be copied asthis word lies always at the point ofintersection of the indicator 2with an imaginary line' passing through' the typing point. Thisarrangement therefore considerably facilitates to the typist the-findingof the word or point to be typed and the 'usual rather troublesomemovement of the eyes between a copy sheet and the paper being typed uponis avoided. ,Itmay be pointed out that the arm 30 is made of resilientmaterial, for'instance, spring steel so that it can bend, under theaction of the line spacing lever 5, after the lever 3 has reached itsend position determined by the screw stop l6. The operation is as,follows: 3 0n actuating the line spacing lever 5, the lower arm 24 ofthe lever 30 is turned and the resilient member constituted by'thespring arm 30 moves, by means 'of cord l3 guided overiroller 3|, theclamping lever 3. The clampinglever 3 is first tilted so as to clamp therod I and is then moved together with the rod l and the indicator 2downwardly, this movement being limited by the screw stop l6. 3 Furthermovement exerted upon the transmitting mechanism duringthe spacing ofthe platen 6, istaken'up bythe spring arm 30, the latter being bentduring the latter part of the movement of the spacing lever 5. After thecompletionof the spacing of the platen 6, the spacing'lever returns toits initial position, and the clamping lever 315 also returned to itsinitial position by thespring 4. During this return movement theclamping lever slides loosely upon therod l, the rod l and'the indicator2 remaining stationary. If the operator wishes to feed the indicator 2without oper'atingth'e spac ,in'g lever 5, he depresses the arm 26' andthus directly operates the cord I3 and the clamping lever 3; The framemembers H) which are di- 7 r'ectly fixedupon the carriage of thetypewriter,

are cQnnectedIby across member 32 and a sheet iron plate 28 which servesas a support for the copy sheet or shorthand book. Between the platen 6and the cross member 32 suflicient free space is left for the passage ofa sheet 29 carried upon the platen of the carriage 21. The cross member32 may be provided with a member acting as the lower support for theshorthand book.

mentof a movable support anda stationary indicator may be used.
